Project: Hadoop YARN
Issue Type: Sub-task
Components: capacity scheduler, resourcemanager
Reporter: Naganarasimha G R

As part of support for sharing NonExclusive Node Label partitions in YARN-3214,
NonExclusive partitions are shared only to Default Partitions and also have
fixed rule when apps in default partitions makes use of resources of any
NonExclusive partitions.
There are many scenarios where in we require pluggable policy like MutliTenant,
Hierarchical etc.. where in each partition can determine when they want to
share the resources to other paritions and when other partitions wants to use
resources from others
